Claims.

` stantaneously pulls on the hand that is caught in an effort to extractit. In the present device this pull swings the wringer and reverses theroll so as to roll the hand out of the wringer. One of the features ofthe invention is to accomplish this operation without being resisted bythe torque thrusts of the wringer so that the necessary effort to swingthe wringer may be independently controlled and thus give the wringerjust the necessary stability for normal use. appear from thespecification and claims.

A preferred embodiment of the invention is i1 lustrated in theaccompanying drawings as follows:

The wringer frameis made up of a base I, side stiles 2, and a top bar 3.rThe wringer has lower and upper ro1ls4 an'd`5 respectively and theserolls are supplied with shafts 6 and- 1 respectively. The lower shaft 6is journalled in bearings 8 xed in the side stiles. The upper shaft 1 isjournaled in bearings III slidingly mounted in the side stiles. A springII operates on the upper bearings to exert pressure on the rolls. It isadjusted in the usual manner by screw I2 operating through a nut in thetop bar. The topbar may be detachable from the side stiles in any commonmanner for release purposes if desired, but this particular feature isnot involved in the present invention and the parts so far as describedmaybe of any of the common forms of wringer.

A post I4 carries the wrlnger. A gear frame Features and details of theinvention will or head I5 has a sleeve I6 rotatively mounted on. theupper en'd of the post. 'Ihe head may be adjusted on the post and lockedin adjustment in the usual manner, namely, the radial Aopenings I1 inthe post and a spring latch I8 Ii in, the head which extends into thesocket I1. There are four of the sockets so that the wringer may beswung to four different positions, as desired. A drive shaft I3 extendsthrough the post. A beveled gear 20 isl journaled on this 10 shaft and asecond beveled gear 2I is also journaled on this shaft. The gears 2|)and 2l mesh with a` common gear 22. The gear 22 has a bearing sleeve 23extending from its hub which operl ates in a bearing 24 in the head I5.

A flexible coupling is arranged -between the shaft 6 and the sleeve 23as follows: A tube 25 extends into the sleeve 23. 'I'he tube is providedwith slots 26 anda pin 21 extends through these slots and into openingsin the sleeve. The tube 25 is slottedat 28 and a pin 23 extends throughthis slot and is fixed in the shaft 6, the openings in the tube 25 beingat right angles to the slots 26 in that tube. This permits the wringerto 'be swung to the positions shown in Fig. '7 in which positions thegears are released or reversed.

A clutch sleeve 30 is connected with the shaft I9 by splines and grooves32 and 33and is, therefore, free to slide on thevshaft vertically, butis locked against rotation with respectto the same. This sleeve hasclutch notches 34 at its ends which engage projections 35 on the gears20 and 2|, these notches and projections forming what is commonly calledjaw or detent clutches. The reverse sleeve 30 has an annular groove 36arranged in it. A sliding block 31 operates in this groove. A crank pin38 locks the sliding block 31 with a crank'33. The crank 39 is'providedwith a shaft 40. The shaft 40 is journaled in a bearing 4I in the frameor head I5. A gear 42 is fixed on the outer end of the shaft 4ll`a ndmeshes with a segmental gear 43. The segmental gear is pivotally mountedon a pin 44 extending from the rame I5. The gear has a slot 45 throughwhich a pin 46 extends. The pin 46 extends through an opening 41 in ashell or case 48. The`pin 46 is screw-threaded and a nut 49 is arrangedon the inner side of the shell and operates with a head 50 of the screwto clamp the pin in the Wall. (See Fig.. 5.)

'I'he case has a bottom section 5I which is provided with a ring 52forming a bearing on the sleeve I6. 'I'his lower section is secured tothe upper section by screws Sla which extend upwardly through the bottomsection into` bosses f `a in the upper section. The upper part of thecase has a socket Il which is iournaled'on a projection 54 in the upper-part of the frame.v

The boss 5I contains a\bearing socket vMa. for the upper end oi' theshaft i9. A mounting plate il is secured to the stile, and the case Ilhas .extensions 56 which are secured to the mounting plate 55. 'I'hus itwill be seen that the wringer is mounted on the case and that the caseis joumaled on the head and that the head is adjustable on the post;

The normal position of thenwringer is away from the operator asindicated in dash lines in Fig. 7. This engages vthe gears for a forwardrotation of the rolls away from the operator. II the operator becomescaught, the operator pulls the wringer toward her, carrying the wringerto a neutral position at the center, and if the pull is continued, tothe reverse' position shown in Fig.v 7. It will be understood that thewringer may be swung in either direction and that the wringer rolls willbe rotating in a forward direction for the operator, positioned withrelation to the wringer, with the wringer swung away from the operator.

While I have shown this mechanism to operate with the pulling of thewringer toward the operator, it will be understood that this may bereadily shifted so that the normal position may be toward 'the operatorand the release accomplished by a push of .the wringer away from theoperator. 'I'his would be accomplished by a mere reversal of the segment43 from a position above the gear I2 to a position below it.

In order that the wringer may be retained so as to satisfy normalrequirements in the set position I provide a yielding detent mechanismbetween the case or shell and the frame. For this purpose an arm 51extends toward the wringer lfrom the frame. This arm is provided with anlone of the rolls; the combination with the frame,

rolls, head.' reversing gearing and drivingconnection of a connectionbetween the frame and the head supporting the frame from the head, saidconnection yielding to permit movement of the frame and with it bothrolls relatively to the head, said connection comprising devicesmaintaining the axes of the rolls in vertical planes; and meansoperatively associated with the reverse gearing comprising a crankresponsive to said yielding movement of the frame reversing the drivingdirection of the gearing.
